Among the 50.7 million Hispanics in the United States, nearly two-thirds (65%), or 33 million, self-identify as being of Mexican origin, according to tabulations of the 2010 American Community Survey (ACS) by the Pew Hispanic Center, a project of the Pew Research Center. No other Hispanic subgroup rivals the size of the Mexican-origin population. Puerto Ricans, the nation’s second largest Hispanic origin group, make up just 9% of the total Hispanic population in the 50 states and the District of Columbia.
Overall, the 10 largest Hispanic origin groups—Mexicans, Puerto Ricans, Cubans, Salvadorans, Dominicans, Guatemalans, Colombians, Hondurans, Ecuadorians and Peruvians—make up 92% of the U.S. Hispanic population.2 Six Hispanic origin groups have populations greater than 1 million.
Hispanic origin groups differ from each other in a number of ways. For instance, U.S. Hispanics of Mexican origin have the lowest median age, at 25 years, while Hispanics of Cuban origin have the highest median age, at 40 years. Colombians are the most likely to have a college degree (32%) while Salvadorans are the least likely (7%). Ecuadorians have the highest annual median household income ($50,000) while Dominicans have the lowest ($34,000). Half of Hondurans do not have health insurance—the highest share among Hispanic origin groups. By contrast, just 15% of Puerto Ricans do not have health insurance.
